关于Unity启动时间过长(启动黑屏时间长)的问题
来源:互联网 发布:启发式搜索算法代码 编辑:程序博客网 时间:2024/04/30 15:29
好吧,Unity启动确实比其他引擎生成的游戏包慢些。关键是你启动的时候还要等上一段时间才显示Splash那个logo图。
最近项目有个蛋疼得需求,需要在启动界面加进度帧动画。。我也是醉了。
刚开始的思路:用Unity单独做个启动场景,让Splash那张图用成纯黑。那么问题来了,除了Unity刚启动的黑屏+显示Splash的黑图,再到显示loading动画界面至游戏场景加载出来,这时间都在十多秒以上了,。项目要求游戏从启动到显示游戏场景不能超过5秒。。哎。。太难为我了。好长一段时间都没能解决这个问题。
中间还想到一个方案就是用Android做一个插件的启动Activity场景,然后把这个场景设置成启动场景,之后再到Unity的场景。但是这个问题是无法绕过Unity的启动Splash。。无奈放弃。
因为不熟悉Android开发,所以。。。
我分析了Unity生成Android,对就是从Unity的UnityPlayerActivity入手。既然绕不过,那就不绕过,思路:
1、Unity生成的Android应用必然要从这个UnityPlayerActivity启动,那么他的启动Splash view必然显示在这个activity里面;
2、那么我可以继承UnityPlayerActivity,然后在onCreate方法里面在创建一个view来覆盖Splash,是的。这是可行的。激动。。。。。。
3、那这个启动界面上我们也同样可以做动画咯,O(∩_∩)O哈哈~现在的问题是当Unity Splash显示完毕之后,或者初始化完成之后怎么来隐藏我们所创建的View和动画。
4、现在我们要在Unity建一个空场景用来加载我们的第一个游戏场景,当加载完成之后通知我们的自定义Activity移除我们创建的界面和动画,是不是很完美呢?
现在不用看黑屏了,也绕过了Unity的Splash,只是加载的时间还是比其他引擎慢了,不过也能接受,因为很快的 就开到了我们的启动动画界面,等待加载到游戏场景。
最后贴点代码上来。。。。

- using System.Collections;
-
- public class Launcher : MonoBehaviour
- {
- public string loadScene;
- void Awake()
- {
- Debug.Log("Launcher Awake");
- DontDestroyOnLoad(gameObject);
- }
- void Start()
- {
- Debug.Log("Launcher Start");
- StartCoroutine(LoadSence());
- }
- IEnumerator LoadSence()
- {
- if (!string.IsNullOrEmpty(loadScene))
- {
- Application.LoadLevelAsync(loadScene);
- }
- else
- {
- int levelCount = Application.levelCount;
- int curLevel = Application.loadedLevel;
- if (curLevel + 1 < levelCount)
- Application.LoadLevelAsync(curLevel + 1);
- }
- yield return 0;
- Invoke("OnFinish", 0.5f);
-
- }
- void OnFinish()
- {
- if (Application.platform.Equals(RuntimePlatform.Android))
- {
- using (AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
- {
- using (AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity"))
- {
- jo.Call("HideSplash");
- }
-
- }
- }
- Destroy(gameObject);
- }
- }
最后把我们的Android项目生成jar包供Unity使用anim文件夹放了动画得的配置文件,layout布局文件。
